I can't imagine an economical way to get to 16 Gigs without 8 SIMM  
sockets, and that many SIMM sockets would eliminate dual CPU boards in  
ATX form AFAIK. You may have to up the PS as well, making it an  
expensive upgrade, on a par with the price of a new system... I  
understand wanting to keep the case, but that and the DVD drive may be  
all you keep.

An i920 or i750 board with lots of DDR3 RAM and bigger PS would make a  
GREAT upgrade, but at $600-750US it is close to the price of a similar  
'store bought' system. Of course, I'd fill the two SATA bays with 1 TB  
WD Black drives at $100 ea.

That's how we roll here at Chez Peterson...
